CD54HC74F3A datasheet by Texas Instruments

CD54HC74F3A Frequently Asked Questions (FAQs)

• What is the recommended operating voltage range for the CD54HC74F3A?
  The recommended operating voltage range for the CD54HC74F3A is 2V to 6V.
• How do I ensure that the flip-flops in the CD54HC74F3A are properly initialized?
  To ensure proper initialization, it is recommended to assert the Master Reset (MR) input low during power-up or when the device is first powered on.
• What is the maximum clock frequency that the CD54HC74F3A can handle?
  The maximum clock frequency that the CD54HC74F3A can handle is 25 MHz.
• Can I use the CD54HC74F3A in a 3.3V system?
  Yes, the CD54HC74F3A is compatible with 3.3V systems, but ensure that the input signals are within the recommended voltage range.
• How do I handle the asynchronous reset input (MR) in the CD54HC74F3A?
  The asynchronous reset input (MR) should be asserted low to reset the flip-flops. It is recommended to use a pull-up resistor to ensure the input is at a valid logic level when not asserted.
